Description of the Related Art In a reinforced concrete building, sleeves (mainly paper cylinders) are preliminarily provided on the floor, walls, and beams of a formwork in a route through which pipes pass. Then, insert a sleeve that is 2 sizes larger (in units of 25 mm) of the pipe outer diameter. In the floor sleeve, when the concrete was hardened, the formwork was dismantled and the sleeve was removed.
A pipe is passed through the hole of the size-up, and the gap is filled with a mortar receiving plate from under the floor (the ceiling surface of the lower floor) to fill the mortar.

を招くものになっていた。As described in the prior art, the repair work for filling mortar after pipe penetration is a dangerous work on the floor, that is, the ceiling surface of the lower floor. Due to legal problems, the mortar must be completely installed. In order to fill the mortar without gaps, it is necessary to produce a mortar receiving plate that fits the outer diameter of the pipe. In addition, it is a work that requires time and skill, such as fixing and supporting the mortar receiving plate so that it does not fall down by the weight of the mortar,
After the mortar is fixed, the work of removing the mortar receiving plate is involved, and it must be finally treated as garbage. In addition, there is no medium (piping or the like) for supporting the mortar receiving plate in a hole that becomes unnecessary due to a change or the like, so that it is difficult to attach the mortar receiving plate. The above work involved a wide variety of construction sites for one building, and the proportion of the whole work process was very large, resulting in large time loss and high cost.

る。本実施例の効果は請求項1の実施例と同じである。In the concrete construction method, a heat insulating material (eg, styrofoam) is often laid on the floor of the first floor and the wall near the upper floor for the purpose of preventing dew condensation. For simplicity and efficiency, there is an increasing number of construction methods that omit the formwork, assemble the floor base using columns and metal pipes, lay styrofoam directly on top of it, and cast concrete.
In this method, when the sleeve is fixed, since there is no formwork below, it cannot be nailed and fixed to the rebar as in the past, but it was troublesome and the stability was poor, and it was difficult. The present invention cuts out the styrofoam, inserts the sleeve fixing device with the bottom plate into the styrofoam, stabilizes it on the styrofoam with the flange (4), also serves as a fall prevention, and can be fixed simply by inserting the sleeve,
After penetrating the pipe, the styrofoam is cut into two pieces, cut into two parts and dropped from the top, and the hole is filled to solve the problem of dew condensation. Becomes possible. The effect of this embodiment is the same as that of the first embodiment.
